About Callus - Climbing Log
Callus is a climbing training log for climbers who train with intention. Log hangboard work, pull strength, sends and attempts, and project sessions — then read your season on a map-inspired dashboard. LOG WHAT MATTERS • Hangboard — edge depth, load, sets, hang time, and session quality • Pull strength — weighted work and bodyweight reps with automatic % bodyweight • Climbing — grades, sends, attempts, session counts, and optional project links • Notes and custom entries for mobility, rehab, or anything else in your plan SEE YOUR TRAINING • Home — PRs, latest send, training mix, and recent volume • Stats — hangboard peaks by edge and pull strength summaries • Charts — grade progression and session trends over time • Path — goal-grade benchmarks, weakness radar, and waypoints • Projects — linked sessions with automatic send detection CLIMB WITH YOUR CREW (optional) • Find real climbing gyms and crags near you on a map styled like a topo sheet • Plant a flag to show your crew where you're headed — and see who else is out • A shared calendar of check-ins, plus crew and per-gym session chat • Private by design — only your crew sees your flags.
